Power consumption is a very crucial aspect of a graphics card and now-a-days it pays a huge factor in making it successful. If a graphics card performs well but has high power consumption, it might not end up being a popular product for example NVIDIA’s Fermi graphics cards. They were good in terms of performance but their power consumption made critics and customers unhappy.
We measure power consumption of each card by playing Sniper Elite, Battlefield 3, Far Cry 3 and Metro 2033 for 20 minutes each and final number is average of all the runs. The numbers represent the total power consumption of our test setup, not of the graphics card only.
